Specification of Letters Patent. Patented lIay 10 1910, Application filed July 6, 1909. Serial No. 506,216.

To all wlwm it may concern: E igure l. is a s i de elevation of a type of Be it known that I, nconn Rnc'roiio'f lamp having my improvements applied the city, county and' state .of New York, thereto. Fig. 2 1s an enlarged detail sechave invented a ,new and useful Improvetional view showing the arrangement of the 'S nient in Gas-Lamps, of which the following float valve, and Fig. 3 is a cross section on 60 is a full, clear, and exact description. I the line 33 of Fig. 2. My invention relates to improvements in The gas lamp 10 can be of any approved gas lamps, and more particularly to vso-called kind, but as stated is usually of the inclosed gas are lamps, although the style of the lamp are type having a globe 11 which rests on 10 1s not absolutely essential. My invention a suitable allery 11, andan exhaust pipe 65 is, however, especially applicable to lamps 12which-delivers to a main pipe 13, and which are generally arranged in series and the latter'can connect with any number of which are adapted for store,'hall, or street lamps and with an exhaust fan or other lighting more particularly, but as above means for exhausting the gases from the. 15 stated, the improvementcan be applied to globe 11. Theflamp is equipped with s70 various forms of gas lamps. The lamp to mantle 14, but obviously any number of which it is best adapted is-of the kind stated, these mantles can be used, and any preferred and those lamps I have generally made with form of mantle or any means of supporting, inclosed globes connected with an exhaust them can be adopted without affecting the pipe and with a series of lamps connected principle of my invention. The main gas 75 with a'single exhaust. pipe, so that products supply for the mantle or mantles flows in of combustion will be exhausted from the through a Bunsen tube 15, and a small pilot globe and the fresh air allowed to flow in tube 16 also leads in to the lamp above the with the gasat the Bunsen tubes. Such Bunsen tube, and is permitted to have suflamps make a brilliant li ht, but they are ficient gas flow to maintain a tiny gas '80 apt to be rather inaccessib e, and the object flame at the base of the mantle. The pilot of my invention is to providea simple means tube 16 can connect with the main supply whereby suchlamps can be automatically in any suitable way, but I have found a and simultaneously lighted or turned down, convenient connection to be by means of the and to provide means of this nature which short tube 17 and valve 18, the connection 8 will also permit of individual lamp controls being with the main gas supply pipe- In carrying out. this idea, I provide a small 19, and this is' preferably though not necespilot jet for each lamp, which is kept burnsarily dropped from overhead. The =mainmg, and have the main gas inlet to each pipe 19 supplies the Bunsen tube 15, and lamp closed by a float valve so that when the the gas supply is controlled by a common 90 exhausting means is not in operation the form of cock or valve 20. float will drop and the maingas' supply be Above and 'formingan extension 05th: shut off, but when the exhausting means is Bunsen 15, is a cylinder 21 in which 1, started, the partial vacuum caused will cause arranged a float 22 which is preferably prothe several floats to rise-and permit the vided with perforations 23 through 'which gas to flow readily and light the lamp. Obthe gas' can pass, and the wall of the; cyli'nviously this idea can be carried out as apder is also inclined outward on the inner plied to one lamp or-to a whole series of side as shown at 24, so that when the float lamps, but it is usual to :1 ply the invention is raised to the position shown by dotted to a series-of lamps, and the character of lines in Fig. 2, the gas can flow along the 1 a the lam s can be varied indefinitely, so long edge oft-lre float. The floathas a stem 25 as they ave exhausting means bywhich the which. extends through a suitable guide 26, float can be operated. and the lowerend of the stem termmates in The invention will be fully understood 'a. valve 27 which seats in the gas openin 0 from the description which follows. 28 which su plies the lamp. Under normal 1 5 Referenceis to behad to the accompanyconditions t o float 22, together with the ing drawings forming a, part -of this specistem 25 and valve 27 are sufficiently heavy fieation, in whichsimilar reference characto overcome the 'wei ht, of gas pressing tors indicate corresponding parts .in all the against the small valve 1n the restricted openviews. in 28 but when a artial vacuum is created e a P in the globe 11 by starting theexhausting means connected with the pipes 13 and 12, the float 22 rises induced by the lessening of pressure on the back of the valve27, and so the gas su ply flows freely-in and as it enters the g e e is ignited from the pilot flame issuing from the tube 16. It will thus be seen that the lampsare all controlled by the stopping andstartim ofthe'exhausting means connected with the exhaust ipe.

It will also be seen that any particular amp can be out out or in as desired by means of the valve 20,'as usual. From the foregoing description it will be seen that I have fprovideda very simpleand positive means r rendering gas lamps automatic'as to their lighting,'and that each individual lamp is perfectly controlled. It will also be understood that the style of lamp has nothing to do with the invention except that it must be 'of such a nature as to permitof 'at' least'a partial exhaustion so as to cause the operation of thejvalve27.

The style'of-float'22 and the particular type of'valve and its support,is 'nbt,'-ho\vever;

essential, although I prefer the 'forms'indh} cated. 5

It will be noticed that some of thedeta'ils' of construction can be c'lia11ged,as,for in-[' 2.
